ART Bay Area

Project Resilience Goals Preamble

Draft Preamble

ART Bay Area

The Adapting to Rising Tides Bay Area project is a regional adaptation planning process focused on regional assets and

• issues. Although regional in scope and scale, the resilience of

the region depends upon the resilience of local communities. Because of the interdependence of the regional and local scales, the following resilience goals reflect issues at both scales and are intended to be used in a way that acknowledges the similarities and differences among the region’s local communities and the importance of the scales.

Draft Project Resilience Goals

Society and Equity

ART Bay Area

Protect and improve Bay Area communities’ ability to access services, affordable and safe housing, a healthy environment, diverse jobs, transportation, information, and opportunities for advancement. Focus on identifying and assisting vulnerable communities who endure disproportionate environmental burdens or exhibit socioeconomic characteristics that increase their risk to hazards.

Draft Project Resilience Goals

Environment

ART Bay Area

Preserve and enhance healthy and vibrant ecological systems to provide multiple benefits, including habitat for native and endangered species, biodiversity, clean water, flood protection, and recreation to maintain high quality of life for natural and human communities. Mitigate environmental risks, such as contaminated lands and poor air quality, and encourage emissions reductions through transitioning to alternative forms of transport and energy to minimize the effects of future climate change. Promote the long-term vitality of natural areas, including wetlands, tidal marshes, creeks, and transition zones, by ensuring they remain resilient and adaptable in a changing future climate.

Draft Project Resilience Goals

Economy

ART Bay Area

Create and support vibrant local and regional economies that provide living wage jobs, tax revenues to cities, affordable housing, goods, and services, are adaptable to changing conditions, and are supportive of both local and global businesses. Focus on maintaining the function of regional job centers, recreation and tourism destinations, transportation networks, and infrastructure. Maintain robust local linkages in a multi-modal transportation network to deliver people, goods, and services throughout the region, nation, and world.

Draft Project Resilience Goals

Governance

ART Bay Area

Build capacity for resilience in local and regional Bay Area communities, agencies, and non-governmental and private

• rganizations by facilitating broad participation at critical points in

climate adaptation processes, including scoping, framing, decision making, program development, and project implementation. Understand and improve upon on current governance challenges by building consensus around appropriate and distinct areas of responsibility for regional entities and local jurisdictions. Build collaboration within the Bay Area by forming coalitions, collaboratives, and JPAs among agencies, organizations, and communities to address issues of flood protection, environmental restoration, infrastructure maintenance, and affordable housing.

meetings where appropriate

• Other ways to engage: on-line or

telephone town halls, etc.

RWG request: Sign up for a Communication Subcommittee meeting to assist the PMT with refining the public participation plan, communication approach and identifying community groups to engage

ART Regional Sea Level Rise Maps

• Uniform mapping for all 9 counties

including 10 total water level scenarios of current and future flooding

• An effective planning tool to:
• Communicate temporary and

permanent flooding

• Identify low spots on the

shoreline that can lead to inland flooding

• Stakeholder reviewed and

validated

• High resolution topographic data

(1 meter DEM)

ART’s One Map = Many Futures

Source: AECOM

• Uses an equivalent water level approach to reduce the

number of maps needed to understand flooding

• Communicates that areas that may be permanently

inundated will first be temporarily flooded

• Provides information that allows local jurisdictions and

agencies to develop thresholds for action

100-year storm surgeà 1/100 chance of occurrence in any yearà 1% chance The smaller the chance of occurrence, the larger the storm, the larger the area flooded.

Projection: Universal Transverse Mercator NAD83 Zone 10N The inundation maps and the associated analyses provide a regional-scale illustration of inundation and coastal flooding due to specific sea level rise and storm surge scenarios, and are intended to improve sea level rise awareness and

• preparedness. The maps are not detailed to the parcel-scale and should not be used for navigation, permitting, regulatory, or other legal uses. Flooding due to sea level rise and storm surges is possible in areas outside of those predicted in

these maps, and the maps do not guarantee the safety of an individual or structure. Nor do the maps model flooding from other sources, such as riverine or surface water flooding from rainfall-runoff events. The contributors and sponsors of this product do not assume liability for any injury, death, property damage, or other effects of flooding. The maps relied on a 1-meter digital elevation model created from LiDAR data collected in 2010 and additional survey data (where available). Although reasonable care was taken to capture all relevant topographic features and structures that may impact coastal inundation, it is possible that structures may not be fully represented, especially those that are narrower than the 1-meter horizontal map scale. The maps are based on model outputs and do not account for all of the complex and dynamic San Francisco Bay processes or future conditions such as erosion, subsidence, future construction or shoreline protection upgrades, or other changes to San Francisco Bay or the region that may occur in response to sea level rise. These inundation maps should not be used for detailed design or construction and users should consult a licensed engineer for information regarding existing and future flood risk at an individual site.

ART Bay Area

What is the Assess Step?

• A step-wise exposure analysis that

saves time and resources by pinpointing the most pressing issues and areas to explore further

• Assessment questions that help

efficiently gather information needed for action identification

• Review and validation of

assessment outcomes by stakeholders, asset managers, local and topical experts

The assessment has three parts:

The assess step builds upon the decisions made in scope and organize and is a critical part of the filtering process of what gets carried through to the adaptation responses and prioritizing action phases

ART Assessment Questions

Assessment questions are a tool to efficiently gather information about vulnerability and risk

• Preliminary answers are

gathered using readily available data, reports and studies

• Findings are validated by

ART Bay Area

ART Assessment Questions

Existing conditions questions describe the asset or asset category and highlight any current conditions

• r stressors that could affect its vulnerability

Examples

• Where is the asset located?
• Who owns and manages it?
• What are the underlying

conditions (seismic vulnerability, lack of funding, displacement, contaminated lands, etc) that are important to consider?

ART Bay Area

EXISTING CONDITIONS: PDAs

• Presence of affordable housing in

surrounding area

• Presence of housing and

transportation cost burden in surrounding area

• Type of PDA (City center, mixed

use corridor, regional center, suburban center, transit neighborhood, transit town center, urban neighborhood) and primary goal (housing, jobs, transit center)

• Surrounding land uses and

community facilities

ART Bay Area

Information questions determine if data or information is lacking, incomplete, poorly coordinated, or difficult to access

Examples

• What types of information sources are

publicly available?

• What is the quality of available information?
• What types of mechanisms exist to share

information between owners of connected infrastructure?

ART Assessment Questions

ART Bay Area

INFORMATION: State/Interstate Roads

• Most Caltrans planning-grade data

(e.g., the location of storm drain and bridge crossings) is readily available and can easily be shared

• Caltrans design and survey-grade

data (e.g., as-built plans with elevation information) can be challenging to access because they are created and stored on a project-by-project basis

• Caltrans has a searchable

repository of records (e.g., as-built and layout plan sheets), however these are shared as PDFs that are not geo-referenced

ART Bay Area

Governance questions identify challenges with management, regulatory authority, or funding

• ptions for adapting to impacts

Examples

• What systems are in place to manage

the assets?

• What funding sources exist that can be

used for adaptation?

• What types of permits are needed to

make changes?

ART Assessment Questions

ART Bay Area

GOVERNANCE: Communities

• What capacity do the non-profits, faith-based

and community based organizations in the project area have to actively participate in adaptation planning? What processes are in place for the local jurisdiction and these groups to engage in existing planning and decision making?

• If the community is protected from flooding by

land or assets owned or managed by others (e.g., structural protection, roadways, rail embankments), what is the relationship between the asset owner/manager and these entities? Do they coordinate information, funding or decision-making?

• Local plans (General Plans, Hazard

Mitigation Plans, etc.) that are in process, or soon to be in process, of updating? ART Bay Area

Examples

• Does the asset provide functions or

services that are limited?

• What services does the asset rely on?
• Is it physically connected to other

assets such that failure in one part of the system disrupts the entire system?

Functional questions consider the function of the assets and their relationship to or dependence

• n other assets

ART Assessment Questions

ART Bay Area

FUNCTIONAL: PCAs

• Does the PCA provide or protect habitat

for threatened or endangered species?

• Would disruption from flooding

potentially impact the open space/wildlife/habitat network’s ability to function?

• Does the PCA provide recreational
• pportunities that are unique or limited

in the area and/or region, e.g., access for persons with limited mobility, interpretive programs, access to the Bay, etc.? Could functions be easily replaced in other areas?

ART Bay Area

Physical questions identify conditions or design aspects that make an asset particular vulnerable

Examples

• To what extent is the asset exposed to tidal, wind or

wave erosion or scour?

• Does the asset have openings are at-grade or below-

grade that are entry points for flooding? Are there pumps

• r other systems in place to remove floodwaters?
• What water- or salt-sensitive components of the asset

are located at- or below-grade?

ART Assessment Questions

ART Bay Area

PHYSICAL: Transportation

• Does the asset have openings are

at-grade or below-grade that are entry points for flooding, e.g., entryways, tubes, tunnels, ventilation grates?

• Has the asset been impacted by

flooding from storm surge or large rain events? What components were impacted? How? (e.g. flooding of components, groundwater intrusion)

• Was the asset designed to be

exposed to salt water? For what period of time?

ART Bay Area

Consequences questions informs how climate change may impact society and equity, the economy and environment.

Examples § How would the community, particularly at-risk members, be affected by damage, disruption,

• r loss of asset function?

§ What critical emergency services would be affected if the asset was damaged, disrupted

• r failed?

§ If the asset was damaged, disrupted or failed would there be a loss of public access, recreational, educational or interpretation?

ART Assessment Questions

ART Bay Area

CONSEQUENCES: PCAs

• Are any of the vulnerable habitats scarce

in the region? Could the habitat be established in other areas?

• What would consequences to ecological

services be if the PCA habitat is damaged

• r lost (e.g. habitat or species benefits,

public access to the shoreline, or water quality)? What would the effect of this loss be locally? Regionally?

• Are the surrounding communities/users of

the PCA underserved in terms of open space/green/recreational areas? How would the potential disruption or loss affect the PCA users and stakeholders?

ART Bay Area

Preliminary Assessment Answers

• Using readily available

data, maps, studies

• By contacting working

group members for additional information

ART staff has begun to compile preliminary assessment information

Asset List Revisited

ART Bay Area

While the assessment step will help us identify the vulnerable assets, we return to the initial problem: the region is big and the assets and assessment questions are numerous.

The region is large Each city has a lot of assets!

Proposal:

• Evaluate and use completed assessments
• Short list of assessment questions that will

build toward indicators

• RWG participation in assisting in the

development of indicators

• Use indicators to

assess at regional scale

• Deeper assessment

conducted with selected assets

Engagement Exercise Understanding Vulnerabilities and Dependencies

• Identify the relationships and connections among

assets

• Explore the vulnerabilities of assets, particularly those

related to asset function and connections

• Discuss the consequences of the vulnerabilities and

how they affect different assets, sectors, and scales

• Provide input on most important characteristics

(indicators) to consider during the assessment

ART Bay Area

Vulnerabilities and Dependencies Engagement Exercise Report Back

ART Bay Area

• Did your table uncover any surprising relationships
• r dependencies?
• Were the dependencies and relationships among

the assets included in the project identified and highlighted at all? Where there critical assets that are not part of the project that people feel need to be considered?

• Which three to five characteristics were identified

by your table that the ART team and the PMT should consider highlighting in the short list of assessment questions? As indicators?

Next Steps
